1/6 percussion 
1/3 wood winds = 2/6 (which is twice as many as percussion) 
1/2 brass = 3/6 (which is three times as many as percussion)

So percussion = 3
wood winds = 6
brass = 9
all together = 3 + 6 + 9 = 18

Pls help me im confused! <br> angle #1 = x = ?<br><br> angle #2 = X + 30 = ?

When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other. The measure of ∠1 is 30°, while the measure of ∠2 is 60°.

<h3>What are Complementary Angles?</h3>

When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other.

for example, ∠x + ∠y = 90°, therefore, the ∠x and ∠y are the complementary angles of each other.

Since the two angles together form a 90° angle. The angles are complementary to each other, therefore, we can write,

∠1 + ∠2 = 90°

x + x + 30 = 90°

2x = 60°

x = 30°

Thus, the measure of the angles can be written as,

∠1 = x = 30°

∠2 = x+30° = 60°

Hence, the measure of ∠1 is 30°, while the measure of ∠2 is 60°.

Draw a line through each point using the given slope. What do you notice about the two lines? Slope = 1/2
Marysya12 [62]
I believe what it is asking is that you draw a line through one point using the given slope. Then you do the same for the second.

If you did this right you should notice that the lines are parallel die to the fact that they have the same slope.

A student scores 74,87,68,63,76 on his last five exams. His teacher will drop the lowest grade to compute the student's average.
den301095 [7]

Answer: 76.25

Average is the sum of numbers divided by the number of numbers

74 + 87 + 68 + 76 = 305

305 / 4 = 76.25

loris [4]
Alright, subtract 2x from both sides, then subtract 6 both sides.
You'll get 4x=-16
Divide -16 by 4
